CI Pipeline Configuration Linter

Build a command-line tool that parses YAML-based CI pipeline configuration files, validates them against a schema of allowed stages and job dependencies, and reports errors like circular dependencies. Learners practice parsing external DSLs, graph algorithms for dependency cycles, and building a validation framework.
